Origyn

Origyn is a platform to sell digital goods using your World ID and creator provenance and rights using on-chain attestations.

Features :

• Humaness Proofs using World ID
• OP Stack Rollup deployed using Conduit
• On-chain attestations using EAS
• Encrypted data storage using Thirdweb
• Block explorer using Blockscout

1. OP Stack Rollup:

   • Deployed using Conduit
   • This provides a scalable Layer 2 solution for improved transaction speed and reduced costs

2. Smart Contracts:

   • Developed the Origyn Contract as the core of the platform
   • Handles all operations, including direct contract attestations and payments
   • Utilizes a USD token (mock stablecoin) for transactions on the rollup

3. World ID Integration:

   • Implemented World ID for humanness proofs
   • Ensures creators are verified humans, adding a layer of trust to the platform

4. Ethereum Attestation Service (EAS):

   • Integrated EAS for on-chain attestations
   • Used to create products with verifiable creator provenance and rights

5. Data Encryption and Storage:

   • Utilized Thirdweb SDK for data encryption and IPFS storage
   • Encryption process:
     • Files are encrypted using AES-256
     • Server action generates IV (Initialization Vector)
     • Encrypted data is converted to Base64
     • Encrypted object (including filename) is uploaded to IPFS

6. User Interface:

   • Developed a Dashboard for creators
     • Allows creation of products using EAS attestations
     • Provides functionality to track and withdraw earnings
   • Created an Origyn Marketplace
     • Displays product information (name, price, ID)
     • Implements a purchase flow with USD token approval

7. Purchase and Decryption Flow:

   • Users can purchase products using USD tokens
   • After purchase, users can access their purchase history
   • Implemented a decryption process to allow users to download and access purchased digital content

8. Blockscout Integration:

   • Integrated Blockscout as a block explorer for the OP Stack rollup
   • Provides transparency and allows users to verify transactions and smart contract interactions

Notable Implementations:

1. The combination of World ID for human verification and EAS for on-chain attestations creates a robust system for ensuring creator authenticity and rights management.

2. The use of Conduit to deploy an OP Stack rollup allows us to scale along with cost-efficiency.

3. The encryption process using AES-256 with server actions, coupled with IPFS storage via Thirdweb SDK, shows a strong emphasis on content security and decentralized storage.

4. The integration of multiple technologies (World ID, EAS, Thirdweb, Blockscout) on top of an OP Stack rollup showcases a comprehensive approach to building a feature-rich decentralized marketplace for digital goods.
